Specification of Letters Patent.

Patented Sept. 24, 1912.

Application filed January 9, 1912. Serial No. 670,245.

Doors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in doors for ovens and more particularly to such as employ glass panels,-one object of the invention being to provide simple and efficient means whereby an oven door having a glass panel, can be used as a shelf when the door is open, without danger of injuring or soiling the glass panel.

A further object is to provide a guard for the glass panel of an oven door, which shall be so constructed and arranged that a glass panel of maximum size can be employed, and which will cover and protect said glass panel when the door is open and used as a shelf.

A further object is to so apply a guard to the inner side of an oven door having a glass panel, that said guard can be made to cover the glass panel when the door is open, and also so that said guard can be held in position to cover the glass panel when the door is closed.

With these and other objects in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings :Figure 1 is a front view of an oven door embodying my improvements; Fig. 2 is a rear or inside view of the door with the guard over the glass panel; Fig. 3 is a view similar to Fig. 2, with the glass panel uncovered; Fig. 4 is a sectional view on the line m-m of Fig. '2, and Figs. 5 to are diagrammatical views illustrating the various manipulations of which the guard plate may be made susceptible.

1 represents an oven door which may be formed with a bulged portion 2. The bulged portion of the door is made with an elongated opening extending approximately from end to end thereof and said opening may be more than half as wide as the width of said bulged portion. The said opening in the door is closed by a glass panel 3 held in place by suitable fastening means. By making the opening in the door of the relative proportions above stated, a glass panel of considerable size may be employed. The

door is provided at its lower edge with a.

rod, the ends of which constitute hinge pins 4. whereby said lower edge of the door can be hinged to an oven.

It is the common practice to utilize an oven door which is hinged at its lower edgeto the oven, as a shelf (when the door is open) to support cooking utensils. When the door is provided with a glass panel, however, said panel is liable to injury from such utensils or to be soiled or suddenlychilled from damp cloths used in handling the utensils, such sudden chilling being apt to cause the breaking of the glass. To avoid such consequences, I provide a guard plate 5 of sheet metal and hinge it to the rear or' inner side of the door in such manner that it can be made to cover the glass panel when the door is open and efi'ectually protect the same from the weight of utensils withdrawn from the oven and also protect the glass from being soiled or chilled by contact of the damp cloth used in handling the utensil. The guard plate will also be so hinged to the door that it can be made to leave the glass panel exposed when the door is closed, or so that it can be made to cover said lass panel. when the door is closed and the claracter of the food being cooked is such that the glass panel might become spattered, especially during the first stages of the cooking of such food. The connection between the guard plate and the door is also such that either face of said plate may be placed adjacent to the glass panel.

To accomplish the manipulations of the hinge pins 9,mounted in suitable hearings.

on the rear or inner side of the door near the ends of the latter; These bearings may conveniently consist of perforated ears 10 secured to the door. The hinge arms 6 may be made in different lengths and the bearthe guard covering the glass panel) and the ings for said arms on the door may bevariously positioned.

In Fig. 5, the hinge arms 6 are of a length approximately one-half that of the short diameter of the glass panel, and the bearings 10 are located on the door approximately in line with the longitudinal center of the glass panel. With such arrangement, either ace of the guard plate may be disposed next" to the glass panel, as illustrated in Figs. 5 and 6, when the door is open or when it is closed. Instead of locating the bearings 10 for the hinge arms 6, as above described, said bearings may be located approximately midway between the lower edge of the glass panel and the lower edge of the door as shown in Figs. 7 and 8. This construction permits either face of the plate to lie next to. the opaque portion of the door, and one face of said plate to lie next to the glass panel. Instead of making the hinge arms 6 of a, length approximately equal to one-half the short diameter of the glass panel, as above explained, said arms may be made of a length approximately equal to the short diameter of the glass panel, as shown in Figs; 9 to 14. In Figs. 9 and 10 the bearings 10.. for these longer hinge arms 6 are located; approximately in line with the upper edge of the glass panel, and in Figs. 11 and 12 said bearings 10 are located approximatelyin line with the lower edge of the glass panel, while in Figs. 13 and 14:, the bearings 10 for the long hinge arms are located near the lower edge of the door.

In the construction illustrated in Fig. 15,; the arms 6 are omitted and the ends of the rod 7 constitute hinge pins which are mount-i ed in bearings 10 approximately in line with the lower edge of the glass panel. The glass panel being of considerable width, the guard. will project below the hinged edge of the door and enter the oven when the door is closed and the guard dropped to leave the glass panel uncovered. It will be observed that as the free edge of the guard can enter the oven (through the door-opening thereof), I am enabled to employ a glass panel of considerable width, which is very desirable. The door will be held in its closed, position by means of latches 11, each having an arm 12 to engage the oven front, and the guard will hang as above explained, to expose the glass panel. When it is desired to cover the glass panel when the door is closed, as when material is being cooked which is liable to spatter grease during the early stages of the cooking, the guard will be held in position to cover and protect the' glass panel when the door is closed, by means; of arms 13 on the latches 11. It is apparent that when the door has been closed (with ployed.

latches are turned, the arms 19. of said; latches will engage the oven front and the nannies 13 will simultaneously engage the upper edge of the guard. In order that the temperature of the oven may be readily ascertained, a thermometer 14 may be em- For the accommodation of this thermometer, the solid panel 15 of the door will be made with an opening 16. The casing of the thermometer is provided on its back with a plate 17 between the peripheral portion of which and the rear face of the door, suitable insulating materiallS is disposed, and said plate is also provided with ears 19 for the passage of fastening devices for securing the thermometer in place.

Slight changes might be made in the details of construction of my invention without departing from the spirit thereof or limiting its scope and hence I do not wish to I claim as new and desire to secure by Letters-Patent, is

restrict myself to the precise details herein.

1. The combination with a downwardlyu opening oven door having a transparent panel, of a guard plate, and means connecting said plate with the inner side of the door and adapted to afford a free hinge connection for said guard plate approximately in line with one edge of the transparent panel, whereby said plate can be disposed with one edge near the free edge of the door and made to cover the transparent panel either when the door is in its lowered arms constitutinghinged supports for the guard plate and permitting the latter to lie in protective relation to the transparent panel when the door is in its lowered or open position and when the door is in its raised or closed position.

3. The combination with an oven door adapted at its lower edge to be hinged to an oven, said door having a transparent panel,

of a guard plate for said transparent panel, arms pivoted, respectively, to the guard plate and to the inner side of the door, said arms afi'ording a free hinge-connection between one edge of said guard plate and the inner side of the door and permitting the guard plate to lie in protective relation to the transtion, said guard plate having a width sufiicient to project beyond the lower hinged edge of the door.

4, The combination of an oven door havparen-t panel when the door is in open posiing a glass panel, said door adapted to be hinged at its lower edge to an oven, a guard plate for the glass panel, a hinge connection between one edge of said plate and the inner side of the door, and a latch near the upper edge of the door, said latch having an arm to engage the oven and also having an arm to engage the hinged guard plate.
